The far-IR ISOPHOT maps of the spiral galaxies M51 and M101 at 60, 100, and at 175{mu}m are analysed. For all areas in these galaxies the spectral energy distributions can be fitted with a single-temperature emission curve. Colours and dust temperatures were estimated for interesting sub-fields. The temperatures vary between 33K for HII regions, and 28K for the disk, arm and interarm regimes.
